thank you so much im really scared for 27th pmo
All you can control is the preparation. Just relax and solve what you can. Good luck! :-)
Thank you for all the solutionss, tomorrows the qualifying stage. I’m hope I’m going to pass😭😭
Best of luck!
Very Cool
Thanks!

you can actually use euclidean division algorithm to solve for number 1 lol
most definitely! For those interested (and reading comments), you can search for euclidean algorithm and continued fractions. :-)
how is 441 modulo 26 = -1? isnt it 25?
Hi, they are part of the same equivalence class. Hence, they are congruent. You can try to read more about congruence here: www.khanacademy.org/computing/computer-science/cryptography/modarithmetic/a/congruence-modulo
441 can become 25 mod 26, and 25 mod 26 is -1
@deronbutorange 25 mod 26 is 25 ?
when dealing with modulos like this where a is n-1, a will always be congruent to -1
@@2309cora 25 (mod 26) is -1 bc it doesn't have any remainders BUT it is missing 1 more number to become divisible by 26 so yeah
How can you only choose 1 out of 25 when k=2? better yet, why not 26 cuz there are 26 terms to choose for??? help
nvm alr get it thanksss
stay skibidi sigma 😛
Hello, how are you so smart? I'm amazed
Just enjoy math and do lots of it :-) Improvement comes by doing.
nice! I just finished your 26th PMO playlist!
Hope it's been helpful and educational! :-)
Thank you so much!
You're welcome!
Appreciate your efforts guys! 🙏
Thank you 🙌
how did rs=3 and r+s=-2
product of the roots is simply c/a; and sum of the roots is -b/a ... assuming we write out the quadratic in the form ax^2 + bx +c = 0.
is there really no way to optimize the process further...? going through all those values of Ps and Qs seem tedious
If you find a more optimal method, we'd love to hear about it. Thus far, this or roughly similar derivations are what we seem to have stumbled on. Remember, this is the last question of a 3 hr paper, so expect some potential tedious work - where one has to be quite careful.
Nice choice of topic to start with, looking forward to following this series 😊
Hi stemlab - anonymous
hi stemlab -pierce takai
What a genius!
Hello sir! I would just like to ask how did you get the value of A in question number one. And how'd you get the formula? thanks!
c/(bc+1), has to fractional - ie. less than 1. Hence, the only value A can take is 3.
Awesome content, really nicely organised, thank you 😊 (PMO is a great competition)
Hello! I fully support your cause for helping aspiring math Olympiads! Is it ok to ask if you also do solutions of past PMO problems (10th PMO until 25th PMO)? That would be great help for us aspiring students. Thank you so much! ☺️💙
Thanks for the support. We'll see what we can do with the older sets :-)
@@StemlabPH Thank you! ☺️💙🥳
Slight correction at 1:47 ... not "a has to be divisible by b" but "a has to have a shared (non 1) factor with b"... but they are relatively prime.
@StemlanPH Hello! Thank you for these videos! May I ask if you are also planning to do past PMO problems with national stage questions? Thank you so much!
Hi, the initial plan was just qual and areas for this year ... but we'll see if we can do more. The proof questions part of the areas was also published by the organizers, so we left those out :-)
@@StemlabPH Thank you so much! ☺️💙
Hi stemlab! - Evan Lao
Oh, @1:00 I meant combination of non-zero rational powers :-) e^ipi = -1 is an example of a transcendental number raised to "a power" that becomes rational 🙂
What grade is pmo for
The Philippine Math Olympiad (PMO) is open to grade 7-12 students and is organized by the Math Society of the Philippines. It is the oldest and most prestigious competition locally. Check them out at pmo.ph
Just a slight error we noticed. @6.53 when we plugged in 54, there was a mistake in the inequalities. It should be: 14/55 > 1/4 > 13/55 which cross multiplies to 56>55 and 55>52. Sorry about that.
